Jouni Malinen 191d8c4f78 tests: Make wifi_display enforce social channel as operating channel 
Previously, this was assumed to be the case due to default channel
selection behavior. However, that may not be the case with driver-based
preference list processing. Enforce a social channel to be used as the
operating channel here since dev[2] uses social channel only device
discovery and needs to find the GO.
